ANCHOR-BLOCK FOR BUILDINGS.

SPECIFICATION forming part of Letters Patenta No. 415340, dated November 26, 1889.

` Application filed September Zl, 1889. Serial No. 3244348\ (No model.)

.To all whom it may concern:

Be it known that I, iVILHELM KRUSE, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Inprovenents in Anchor-Blocks for Buildings, of which the following is a specification.

The object of n'y invention is to provide a durable and cheap block for mchoring` the joists and girders of buildings to the walls.

The invention will be fully understood fron the following description of the acconipanying drawings, in which like perts are indicated by similar reference-letters wherever they occur throughout the various Views.

My anchor-block is preferably made of fireclay burned hard, but inay be made of any,

strong refractory material which is not liable to expand and contract under Varying conditionsof the atmosphere or temperature.

Referring to the drawings, Figure 1 isa top or plan View of iny preferred form of anchor- Fig. 2 is a rear elevation of the same. Fig. 3 is a top View of a modified form. Figz t is &front elevation of the form of block shown in Fig. Fig. 5 is &vertical transverse section taken through a part of a Wall and centrally through the form of block shown in Figs.1,2, and 7, with a joist shown. anchored in position. Fig. G is a similar view, but having the form of block shown in Figs. 3 and 4 built into the wall. Fig. 7 is a horizontal section of partof a wall, taken in a plane with the top of the anchor-block.

The anchor-blocks A and B are dovetail in shape, so that When built into the walls they are firmly locked in position by the masonry (whether brick or stone) overlztpping the beveled edges of the blocks. Themortar adheres to the fire-clay, forming a perfect bond between the inasonry and blocks.

The block A has grooves or Channels a in its back to receive the upturned end of the iron anchor C, Fig. 5. The opposite end of the anchor is turned inward to enter a seat forned for it in the side of the joist D, to which it may also be Secured by screws or in any We11-known manner. The purpose of having more than one groove in the blockA isto be sure that one or the other of them will be in a position to register with the top of the joists, so that the blocks may be quickly set in position and may be moved one way orthe other to accoinnodate the brick or stone and yet receive the anchor.

The block B differs from block A only in having an upwardly-projectingrib b o rtenon from its front face at the top to enter a transverse groove cut in the lower edge of the j oist, (see Fig. 6,) and thus dispense with the anchor C, the rib b taking its place.

My anchor-blocks are quite as cheap as the wooden blocks connonly used. They are not affected by moisture, nor are they liable to expand and shrink or decay, as are the wooden blocks, and, besides being fire-proof, the walls WILHELM KRUSE.
